| Non geographic atrophy
demonstrating areas of stippled, punctate hypopigmentation of degenerated
RPE, hyperpigmentation and soft drusen. |
|
- Have been referred to as "incipient atrophy" since they
are usually preceding geographic atrophy and are more likely to develop
soft drusen and choroidal neovascularization
- Clinical features:
- Areas of stippled, punctate hypopigmentation of degenerated
RPE associated with pigment mottling
- Thinning of the overlying neurosensory retina
- The underlying choroidal vessels are not more readily apparent
than in normal area without atrophy
- Fluorescein angiogram demonstrates diffuse hyperfluorescence with
a pattern of reticular or punctate blockage in the areas of RPE degeneration
corresponding to the pigment clumping.
